Scratch Start Technique

S-0049

Electrode

Workpiece

Arc

Drag electrode across workpiece

like striking a match; lift electrode

slightly after touching work. If arc

goes out electrode was lifted to

high. If electrode sticks to work-

piece, use a quick twist to free it.

Tapping Technique

S-0050

Electrode

Workpiece

Arc

Bring electrode straight down to

workpiece; then lift slightly to start

arc. If arc goes out, electrode was

lifted too high. If electrode sticks to

workpiece, use a quick twist to free it.
